Tell me how would you respond to the following request.
What type of data structure would you use to store a list of unique subscribers?

To store a list of unique subscribers, a hash table or set would be the most appropriate data structure. A hash table is a data structure that uses a hash function to map data to unique keys, and a set is an unordered collection of unique elements. These data structures are efficient and well-suited for storing a list of unique subscribers.
